HD-A5L multimedia player for LED displays
The Huidu HD-A5L combines stored-program playback and live HDMI input in an LED display multimedia player with up to 1.3 million pixels of loading capacity. Two Gigabit Ethernet outputs connect to HD-R series receiving cards, making it suitable for commercial displays that need both scheduled content and a live source.
Content management and playback
Use the LedArt mobile app over the built-in 2.4 GHz Wi-Fi connection, or manage programs remotely through XiaoHui Cloud. Wi-Fi STA mode lets the player join a nearby wireless network. A 4G/5G module is optional for cellular connectivity.
The player supports videos, images, GIF animations, text, WPS documents, tables, clocks and timing programs. USB connections support program insertion and storage expansion. Mobile phones, tablets and computers can also use wireless projection. External environmental sensors connect through two sensor inputs.

Frequently asked questions
How many LED pixels can the HD-A5L control?
The maximum LED loading capacity is 1.3 million pixels. The specification lists a maximum width of 16,384 pixels with reduced loading capacity and a maximum height of 4,096 pixels. These limits cannot be combined into a 16,384 × 4,096 display. Confirm the intended screen layout before ordering.
Can the A5L play stored content and an HDMI source?
Yes. It supports asynchronous playback of stored programs, synchronous HDMI input and switching between the two. The specification also lists synchronous/asynchronous picture-in-picture operation.
How do I update content remotely?
Use the standard Wi-Fi connection with the LedArt mobile app, or connect the player to the XiaoHui Cloud platform for remote program management. Cellular access requires the optional 4G/5G module.
Does 4K video playback mean the LED output is 4K?
No. Video decoding and LED loading are separate specifications. The A5L supports the listed multi-window video playback combinations, while its LED output remains limited to 1.3 million pixels.
Does the A5L connect directly to LED modules?
Its two LED output Ethernet ports connect to HD-R series receiving cards. Select receiving cards and module connections to match the LED screen; the Ethernet outputs are not HUB75 module connectors.
